Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Custom machinery using aligned 1-1/4-inch keyed shafts
  • Agricultural and industrial drive repairs matching all dimensions
  • Not model-specific

Product Overview

A solid coupler creates a rigid connection between two aligned shafts. It can replace a worn coupling bore or support a new fabrication where both shafts share the same 1-1/4-inch diameter and key arrangement.

This design does not compensate for significant angular or parallel misalignment. Shaft diameter, key size, coupler length, torque, speed, and guarding must suit the application.

Key Features & Performance

  • Bore sized for compatible 1-1/4-inch shafts
  • Keyway supports positive torque transfer
  • Set screws retain the coupler on the shafts
  • Rigid solid-body design

Common Uses

  • Joining two aligned keyed shafts
  • Replacing a coupler with an enlarged or damaged bore
  • Fabricating a rigid low-misalignment drive connection

Technical Specifications

  • Product Type: Rigid Solid Shaft Coupler
  • Nominal Bore: 1-1/4 inches
  • Retention: Keyway and set screws
  • Application: Compatible aligned shafts
  • Condition: New

Installation & Fitment

  • Measure both shafts and the key before assembly
  • Correct shaft misalignment rather than forcing the coupler
  • Seat the key fully and tighten set screws to the design requirement
  • Install appropriate rotating-shaft guards

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Confirm 1-1/4-inch shaft diameter, key width and depth, coupler length, torque, speed, and alignment.

Frequently Asked Questions

Q: Will this coupler handle misaligned shafts? A: A rigid coupler requires close alignment. Use a flexible coupling when the design needs misalignment compensation.

Q: How do I confirm this is the correct solid shaft coupler? A: Confirm 1-1/4-inch shaft diameter, key width and depth, coupler length, torque, speed, and alignment.

Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket product. Brand and model names identify compatible applications only.
